Investigations on radiosensitive and radioresistant populations of Drosophila melanogaster. X. The resistance factor rar-3: genetics.
In earlier work, immature oocytes of the irradiated population ROI4 of Drosophila melanogaster were found to be radioresistant relative to those of the basic population ROI and to those of the control population Berlin wild (+K). The resistance of ROI4 relative to ROI was previously attributed to a hypothetical "factor" rar-3. In the present paper, evidence is presented to show that rar-3 is a single, recessive genetic factor, located on chromosome 3 at a map position of about 49.8. The action of rar-3 is apparently independent of that of rar-1 and rar-2, the factors already present in ROI.
